  • Factors Affecting Ball Mill Grinding Efficiency

    The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills

  • The energy efficiency of ball milling in comminution

    In a second approach, comminution efficiency is based on comparing the energy to produce some size distribution parameter of the product from ball milling with that by single-particle breakage. For both materials, dry ball milling efficiency was found to be in the range of 25%.

    Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
